Application filed January 7, 1910. Serial No. 536,848.

To all whom 'it may concern:

Be it known that I,- HENRY HARLAN Goa, a citizen of the; United States,residing at Prescott, in the county of Walla l/Valla and State ofWashington, have invented certain new and useful Improvements inNeeding- Machines,.of which the following is a specification.

- ThlS nvent-ion has relation to certain new and useful improvements inweeders or cultivators, and hasfor its ob ect to provide a machine ofthis character WhlCll is simply ground of stalks, weeds, vines andothergrowths which are detrimental to the cultivation of various farmproducts. I

A further object is to provide a weeder employing a plurality of 'obliuely positioned knives or blades, a vertical y disposed cutting diskbeing arrangedto operate in conjunction with each of the blades to moreefiiclently perform the cutting action, said blades and disks beingvertically adjustable on the frame of the machine, to properly positionthe same with relation to the ground surface.

With those and other objects in view the present invention consists inthe combination' and arrangement of parts as will be hereinafter morefully described and particularly pointed out in the appended clalms,

it being understood that changes in the specific structure shown anddescribed ma be made within .the scope of the claims wit out departingfrom the spirit of the invention.

In the drawings formin a part of this specification and in whic likenumerals of reference indicate similar parts in the several views,Figure 1 is a top plan view of the machine. Fig. 2 is a section taken online 22 of. Fig. 1. Fig. 3 is a rear view.

Fig. 4 is a fragmentary bottom View. Fig. 5 is'an enlarged sideelevation, showing the manner of securing one of the various cuttingmembers of the machine to its support.

Fig. 6 is an end view of same.

In the preparation of lands for planting purposes it is an essentialrequirement that all weeds, stalks, stubble, or other rank growths beremoved before the seed is sown, so that the plants will derive the fullbenefit of the nutriment contained in the soil, thus greatlyfacilitat-in their healthy and vigorous growths. In t e attainment ofthe above object I have devised unimproved weedin machine whichcomprises the frame 5 pre era'bly constructed of angle iron" and of. U-

shaped form in plan. The ends of this frame are secured upon thetransverse wheel shaft (5, to the opposite ends of which the tractionwheels 7 are secured. A tongue 8 is cen trally securedto the frame, anda drivers seat 8 is suitably secured on the rear end thereof. The shaft6 is bent.near its ter- -llllI1 1lS and extends vertically a short dis?tance and then is bent horizontally so as to:

pass directly over the tongue 8 to which it is The. lower ed to lie in aplane transverse to the vertical plane of the beam. A brace bar 10"extends transversely of the cutter beams and is passed through them nearthe beginning of the curvature 10'.

To t lower extremity of each of the beams a cutting blade 12 is secured.These cuttingblades 12 are in the shape of elongated parallelogramswhich are provided with holes 12 adjacent the shorter edges. Theseblades are sharpened on both long edges so that in case one edge becomesdulled a simple turning of the blade end for end will present a newcutting face to the weeds and stubble, the holes 12 admitting ofsecuring the blades to the cutter bars at'eith'er end. It will be notedfrom'refe'rence to Fig. 1 that these blades are arranged in parallelrelation and at all angle to the longitudinal body portion-0f .thebeams. Owing to the distortion of the rear ends of the beams, theseblades are also obliquely positioned in a vertical plane.

A clamping member 20 is secured to each cutter 'beam 10, and-on this ismounted a vertical arm 21, which is bent laterally as at 21 for a shortdistance and then extended downwardly, its lower end being reduced andscrew threaded, and carrying a nut 2'2. Secured to the reduced ortion ofthe arm 21 by the nut 22 is the bi nrcated arm 23which extends in arearward and diagonally downward "direction. In the lower end of thebifurcated arm is revolubly mounted a disk 13, the supporting membersthereof being so disposed as to bring the forward point of the cutterblade 12, carried by its cutter. beam and the edge close proximity.

Transversely positioned centrally int-he frame, there is a rotatable rod14,to which the lower end of an adjusting lever 15 is secured. Thislever carries a spring actuateddog 16 which is adapted to engage withtheteeth of a rack segment 17 which is secured upon the tongue. The rod14 carries a plurality of laterally disposed arms 18, the outer ends-ofwhich are pivotally connected to a'vertical arm. 19 secured upon each ofthe cutter beams 10. Thus it will be seen that as th lever 15 is movedforwardly or rearwardly, the blades 12 and cutter disks 13 will belowered or raised to any desired position .vith relation to the groundsurface.

In the operation of the machine after the blades have been properlyadjusted, the movement of the machine over the ground will force thecutter blades and disks into contact with theweeds and owing to theirdisposition on the machine, the weeds will be cut close to the ground.The angular arrangement of the blades causes a shearing cut of the sameas they contact with the stalks of tlie plants. Any vines or othermatter which may lie closely upon the surface of the ground will besevered by means of the cutter; disks 13. In this manner the ground may;be rapidly cleared and hartransverse rod secured in the forward end ofsaid frame, a plurality of parallel longitudinal cutter beams hingedlysecured to said red, the rear end of each of said beams I beingdownwardly curved to lie in a plane I transverse to' the vertical planeof the beams,

a transverse brace bar secured to the beams, a cutting blade secured tothe extremity of the curved end of. each of the beams, said bladesextending ,reamvardly of the beams and obliquely thereto, said bladeshaving two edges and being adapted to be turned of the cutter disk inend for endand means for elevating or lowering said blades.

2. A machine of the character described comprising in combination, awheel sup ported U-shaped frame, the rear of said frame being open, atransverse rod secured in the forward end of said frame, a'plurality ofparallel longitudinal cutter beams hingedly secured to said rod,obliquely dis posed cutter blades secured to the rear ends of saidbeams, said blades being disposed ata vertical inclination, a transversebrace bar secured at its ends to each of the beams, a. rod extendingtransversely and secured in the frame, a plurality of laterallyextending arms carried by said rod, a vertical arm secured to each ofsaid beams, said arms being pivotally connectedat their ends, a tonguepositionedcentrally'on the frame, and an adjusting lever. secured at itslower end to said rod and adapted to rotate the rodto raise orlower thecutting blades.

3. 'A machine of the character described comprising in combination, awheel supportfront end of said frame, a plurality of cutter beamshingedly secured at their forward ends to said shaft, the rear ends ofsaid beams being downwardly curved and twist- "ed U-shaped frame, ashaft. secured in'the ed to lie in a plane transverse to the verticalplane of the beams, a cutting blade secured to the extremity of thecurved end of each of the beams, said blades extending rearwardly of thebeams and in oblique relation thereto, a rotatable cutting diskcarriedby each of the beams adjacent to the forward end of the blade atransverse rod rotatably mounted in said frame, a lateral arm securedupon said rod adjacent to each of the cutter beams, said arms beingpivotally connected to the beams, a tongue centrally positioned upon theframe, anradjusting lever rigidly secured at its lower end to the rod, arack segment mounted upon the tongue and a spring actuated dog carriedby the lever adapted to hold said lever in its adjacent position, toretain the cutting blades and disks a ainst vertical movement.
